Secure clamping for cylindrical-shank tools and repeatable results

The ER collet chuck delivers precise axial and radial retention for tools with cylindrical shanks, ensuring repeatability and stable machining results. Compliance with DIN 69871 Form AD guarantees interchangeability with standard spindle noses and tooling systems, so setup variability is reduced. The specified 1–10 mm clamping range accommodates common cutter shank diameters, reducing the need for frequent toolholder changes and helping to maintain consistent concentricity during milling and drilling operations.

Standard conformity for straightforward integration and tool change

Adherence to the DIN 69871 standard means the chuck mates reliably with spindles specified for Form AD dimensions, simplifying integration into existing rigs. The SK40 taper and A = 63 mm projection provide a predictable tool geometry for programming and fixture design. Where tools conform to DIN 6499, the ER collet system ensures firm clamping without additional adapters, supporting faster changeovers and lower setup time in serial production and maintenance workshops.

Productivity gains through robust design and minimal maintenance

A robust clamping interface and standardised taper reduce vibration and tool run-out, which directly improves surface finish and tool life—two tangible productivity benefits. The construction supports frequent tool changes while preserving accuracy, so throughput increases without sacrificing quality. Routine upkeep is straightforward: inspection of the collet and nut assembly for wear and correct seating keeps the system performing within expected tolerances, extending service intervals and lowering total cost of ownership.

Compatibility, workshop versatility and application scope

The chuck suits a wide range of general workshop and industrial machining tasks where cylindrical-shank tooling is used. With a clear D = 32 mm body diameter and ER system compatibility, the holder fits common ER collets and accessories sized for the ER16 designation of the Aufnahme. This flexibility allows consolidation of tooling inventory and supports efficient tooling management across milling centres and toolroom machines, while ensuring that clamping integrity is maintained on both short and extended-reach tool applications.

FAQ

What shank diameters are suitable for this collet chuck?
The TECWERK ER collet chuck supports shank diameters from 1–10 mm, covering common small-to-medium cutter and drill shanks.

Is the holder compatible with standard SK40 spindles?
Yes, the chuck is manufactured to DIN 69871 Form AD dimensions and is compatible with SK40 spindle noses designed to that form.

Which ER collet size does the Aufnahme accept?
The Aufnahme is specified as ER 16 / 426 E, indicating compatibility with ER16 collets matched to the 1–10 mm clamping range.

How does DIN 69871 conformity benefit workshop operations?
Conformity to DIN 69871 ensures mechanical interchangeability and predictable tool projection (A = 63 mm), which simplifies setup, reduces errors and supports consistent machining outcomes with the TECWERK ER collet chuck.

What routine checks preserve performance of the chuck?
Regular inspection for collet and nut wear, correct seating and cleanliness of the taper and collet bore helps maintain repeatability and prolongs service life of the tool holder.
